reorder prompt sections: task-first with dynamic TOC (#513)

* reorder prompt sections: task-first with dynamic TOC

put the actual task at the top of the prompt for primacy, add a
dynamic table of contents, and push system/runtime metadata to the end.

new section order: TOC → YOUR TASK → PROCEDURE → EVENT CONTEXT →
SYSTEM → LEARNINGS → RUNTIME

Made-with: Cursor

* enforce clean working tree: continue session if agent leaves uncommitted changes

after each agent run, check `git status --porcelain`. if dirty, resume
the same session with instructions to commit on a new branch, push, and
open a PR. retries up to 3 times before giving up.

- claude code: capture session_id from result event, use --resume <id>
- opencode: use --continue to resume the last session
- remove --no-session-persistence from claude (needed for --resume)
- update Task mode to clarify branch/push/PR is the default finalize step

Made-with: Cursor

* log full prompt in collapsible group for debugging

Made-with: Cursor

* fix: format tool refs in buildCommitPrompt via formatMcpToolRef

* enforce clean git status: general instructions, stop hook, and Task mode

Made-with: Cursor

* fix: rename stale titleBody references after body leak fix

MCP servers provide tools you can call. Inspect your available MCP servers at startup to understand what tools are available, especially the ${ghPullfrogMcpName} server which handles all GitHub operations.

### Git
Use \`${ghPullfrogMcpName}/git\` for local git commands (status, log, diff, add, commit, checkout, branch, merge, etc.). For operations requiring remote authentication, use the dedicated MCP tools:
- \`${ghPullfrogMcpName}/push_branch\` - push current or specified branch
- \`${ghPullfrogMcpName}/git_fetch\` - fetch refs from remote
- \`${ghPullfrogMcpName}/checkout_pr\` - checkout a PR branch (fetches and configures push for forks)
- \`${ghPullfrogMcpName}/delete_branch\` - delete a remote branch (requires push: enabled)
- \`${ghPullfrogMcpName}/push_tags\` - push tags (requires push: enabled)
Use \`${t("git")}\` for local git commands (status, log, diff, add, commit, checkout, branch, merge, etc.). For operations requiring remote authentication, use the dedicated MCP tools:
- \`${t("push_branch")}\` - push current or specified branch
- \`${t("git_fetch")}\` - fetch refs from remote

- \`${t("delete_branch")}\` - delete a remote branch (requires push: enabled)
- \`${t("push_tags")}\` - push tags (requires push: enabled)
Rules:
- All code changes must be pushed to a pull request (new or existing) before the run ends. This environment is ephemeral — unpushed work is lost permanently. \`git status\` must be clean when you finish.
- Protected branches (default branch) are blocked from direct pushes in restricted mode. Do not use \`git push\` directly — it will fail without credentials.
- Do not attempt to configure git credentials manually — the ${ghPullfrogMcpName} server handles all authentication internally.
- Do not attempt to configure git credentials manually — the ${pullfrogMcpName} server handles all authentication internally.
- Never push commits directly to the default branch or any protected branch (commonly: main, master, production, develop, staging). Always create a feature branch following the pattern: \`pullfrog/<issue-number>-<kebab-case-description>\` (e.g., \`pullfrog/123-fix-login-bug\`).
- Never add co-author trailers (e.g., "Co-authored-by" or "Co-Authored-By") to commit messages.
### GitHub
Use MCP tools from ${ghPullfrogMcpName} for all GitHub operations. Never use the \`gh\` CLI — it is not authenticated and will fail. The MCP tools handle authentication and enforce permissions.
